wheel certification ?

[RX-7_TWINTURBO]

just wondering if there was some kind of wheel certification that approves a wheel for competition track/auto X usage.

do cheaper knowoff wheels like adr, konig, motegi etc.. have a greater chance of cracking under high stress compared to the higher end brands like volk, Oz, racing hart, or are wheels all pretty much the same ?

That a good question for certification.

For awhile Rota was tarnished with problems - lots of problems with track and light autoX usage.

The only certification that I can think of is DOT... But then racing wheels like

:dunno: :dunno:

There are different certifications for certain, that very country to country. Some of the most stringent testing would be from Germany or Japan. The German certification is known as "TUV" approval, while Japan is "JWL". There are many different types of certification as well, but these are three of the most familiar...

As for how well a wheel will stand up to track use, that is a bit different. Quite honestly, most guys want lightweight for the track, and there are a lot of high end companies that make some pretty awesome stuff, but it won't necessarly make it a lot more durable. Lightweight will generally not be as strong and durable overall, and even high end wheels like 3 piece BBS etc can have issues after exposure to regular track use. Generally speaking though, a good forged wheel will give you light weight and better durability to twisting and cracking over a cast wheel, but they are expensive and still not fool proof...

The thing is, most higher race teams don't expect their goods to endure over the long haul. It is considered one of the expenses of racing. But for you and me who only want to play around on the track now and again, this type of rim is overkill. If you get a wheel that passes DOT standards and is what you want, it will be more than durable enough, but anything that get abused (yes, racing is considered abuse) will eventually risk some form of damage or another.
